• Source: Flowability

Flowability, also known as powder flow is a property that defines an ability of a powdered material to flow, related to cohesion.
Powder flowability depends on many traits:

the shape and size of the powder particles due to intermolecular force,
porosity
electrostatic activity
hygroscopy
bulk density
angle of repose
presence of glidants
oxidation rate (of a metallic powder)
humidity
ISO 4490:2018 norm (and its precedent, ISO 4490:2014) standardizes a method for determining the flow rate of metallic powders. It uses a normalized/calibrated funnel, named Hall flowmeter.
